lclaim.

This invention relates to cooking ranges and is particularly adapted toelectric ranges.

It is an object of this invention to provide a ventilating means fortheoven of such ranges.

It is a further object of this invention to so direct the ventilatingduct that its opening into the room shall be away from the walls.

It is a further object of this invention to provide a closure for theexterior end of the ventilating duct which shall have openwork -toafford ventilation.

It is a further object of this invention to provide means whereby theclosure may be readily removed for cleaning or for access to theventilating duct.

It is a further object of this invention to locate the exterior end ofthe duct in the back splasher.

Other objects of the invention and details of the construction will beapparent from the following description and the accompanying drawn inwhich:

Figure 1 is a front elevational view of the range.

- Fig. 2 is an end elevational view of the same.

Fig. 3 is an elevational view of the closure for the duct'and Fig. 4is'an edge view of theclosure.

The range I has an oven 2 closed by a door 3. The top or cooking surface4 of the range is equippedat its back edge with an upright panel 5 whichis the back splasher. It serves to protect the wall of the room fromgrease, smoke or other dirt produced during the cooking.

Inside of the oven an outlet 6 is provided which extends into a duct 1.The duct lhas its other end in the surface of the back splasher. A

back splasher which is the end of the duct I.

This closure is not tight, but is-made in the 40 form ofa grille oropenwork. In the form shown, 7 this grille consists of arched bars 9which extend across the disk 8. The bars extend beyond the front surface.of the back splasher as may be best of openwork may be used instead ofthe bars 9, and it is not necessary that they extend beyond or riseabove the surface of the disk. At the circumference the metal of thedisk is turned in- These fingers are arched outwardly as may bestseenin-Figs. 2 and 4. If desired,'any other form be seen by observing thetop and'bottom fingers in Fig. 4. They frictionally engage the walls ofthe duct at its mouth and thus secure the closure in place.

In the operation of the device, the food to be a cooked is placed in theoven 2 and whatever vapors it produces in cooking emerge from the oven 6into the duct I and thence through the openwork oi the disk 8 into theroom. Since this disk is on that surfaceof the back splasher 10 which istoward the working surface of the stove, the fumes from the oven are notdirected against the wall of the room and conse uently do not mark thewall. This is particularly important when through any accident the foodin the oven is charred and the smoke from the charring escapes throughthe disk. Not only does the smoke not mark the wall, but because itemerges directly into the room, the attention of the operator is quicklycalled thereto and she can attend to the material being cooked beforeserious damage is done. It will, at times, happen that the duct 1becomes fouled with grease, soot or other dirt and must be cleaned. Forthis purpose the disk 8 is removed from the mouth of the duct. The diskcan then readily be cleaned and the duct is accessible, whereby thecleaning of it is more easily accomplished.- When the disk is insertedinto the mouth of the duct the fingers H are slightly bent an inward andtheir frictional engagement with the walls of the duct keeps the disk inplace. The openwork I aflords an engagement for the fingers or for ahook whereby the disk may be conveniently removed from the mouth of the5 duct when necessary.

Although I have specifically described and illustrated one form of thisinvention, other forms will beobvious to those skilled inthe art. Itherefore do not intend the specific description 40 and illustration toact as a limitation. No limitations are intended except those expresslystated in the claim or required by the prior art.

I claim as my invention:

.An openwork disc constituting a duct outlet for insertion in a backsplasher, said disc being dome shaped and having an inwardly extendingflange at its edge, and spring fingers extending from the inner edge oisaid flange into said duct and frictionally eng the walls thereof tohold the disk in the mouth of said duct at the backsplasher.
